Pamela- who is mum to teenage sons Brandon and Dylan- has kept a relatively low profile this year following her divorce from ex-husband Rick Salomon.
After a lengthy legal battle, the divorce was finalised in April 29.
Pam was previously married to Motley Crue drummer Tommy Lee, who she split from in 2008.
